[Printing-architecture] PDFio: Replaced QPDF by PDFio in libcupsfilters as GSoC project?

Hi,

Michael Sweet has closed the PDFio issue in which I ask for support of 
PDF forms and annotations, telling that inside PDFio nothing further 
needs to be done, that everything can be solved outside PDFio, by the 
calling application.

As we want to get rid of C++ in libcupsfilters I plan to let it use 
PDFio where it is currently using QPDF.

Mike, as you tell that PDFio is OK for handling PDF files with filled 
forms/annotations, I want to post a GSoC project idea to switch over 
libcupsfilters from using QPDF to PDFio. WDYT? Is this possible already? 
Or are there still any features missing in PDFio?
